Tite accepted Brazil were under pressure after their winless run continued with a 1-0 loss to rivals Argentina in a friendly on Friday.
Lionel Messi scored the game's only goal on his return to the Argentina team in Riyadh, converting a rebound after Alisson saved his penalty in the 13th minute.
Gabriel Jesus had earlier put a penalty wide for Brazil, who are winless in five games since lifting the Copa America in July.
Tite said there was pressure on Brazil – who face South Korea in another friendly on Tuesday – amid their poor run of results.
"There is a need for the result, yes. There are moments of pressure and this is one," Tite told a news conference.
"The way we are going to look is carefully, but the need for the result occurs, even at a time of preparation."
Brazil were without the injured Neymar, and they are feeling the absence of the Paris Saint-Germain star.
Tite's side have scored just four goals in their past five games and the coach lamented Brazil's inability to take their chances.
"Translating opportunities into goals is key, and I also speak of the penalty," he said.
